If using espconn in ESP8266_RTOS_SDK, please call espconn_init in user_init as initialization.

Sample code below is based on ESP8266_NONOS_SDK.1. Start from user_init2. ESP8266 is in station mode and connect to a router3. Set up a TCP server listening to TCP client4. If TCP server received data from TCP client, it will reply the same data back to TCP client.

Dear Sir I am Dushyant herei have made Vb code for Modbus Tcp/Ip. Which works as Server/Slave as well as Client/Master. Now my software can connect with only one server at one timeso is it possible to be connected for continusly with more then one server?

Hello ,I have noticed some examples found in the help web page for wlan esp8266. One is the TCP server that a PC can connect the the esp8266 access point and switch on off LEDs.The other is the TCP client that the esp8266 connects to home router and accesses matrixs web page.

Is there an example of those 2 combined? It would be good to connect the esp8266 to home router and switch LEDs on off through the internet by enabling port forward on home router.
